The National Weather Service in Jacksonville, FL has forecasted a spate of potentially disruptive weather for the area, issuing a detailed outlook that suggests residents and visitors alike will need to prepare for a week dominated by high temperatures, humidity, and a considerable chance of showers and thunderstorms virtually every day.

Starting today, there's a "40 percent chance of showers and thunderstorms after 2pm," with mostly sunny skies but with heat index values climbing as high as 100 degrees, this according to the NWS Jacksonville's latest update, gusts could surge as high as 21 mph later in the day though tonight, the threat of thunderstorms drops slightly to 30 percent before 8pm with a low around 75 degrees, the westerly breeze maintaining a presence into the evening hours.

Over the weekend, weather conditions will intensify with the chance of precipitation jumping to 60 percent on Saturday and to a steaming 70 percent by Sunday, both days bring with them high temperatures in the mid-90s and the continued risk of thunderstorms, particularly in the afternoon, a common theme that extends well into the next week.

The workweek seems to underline this pattern firmly: Monday and Tuesday both wield an 80 percent chance of rain showers and thunderstorms in the afternoon and evening, and by Wednesday and Thursday, residents can expect little respite as thunderstorms remain in the forecast with persisting 80 percent precipitation chances, the mercury on the thermometer tough to ignore, skirting the low 90s as it will feel even hotter given the unyielding humidity, as per the NWS forecast.
